>What puzzles me is about the grey spots got on the strings. I tend to think >it is a humidity problem, but I have never see humidity to this to the >strings. Rust, yes. Grey spots no. > Hi Dave, You have me confused, Rust on steel no problem, not on copper. Grey on copper???? Most common polutants turn them a greenish like colour. Almost sounds like the copper plated aluminum strings of yesteryear. Try rubbing one of them with some fine wet and dry, down near the swage, see if you get nice bright copper. If they turn shiny grey, plated strings, and probably a plating problem, that may give you a clue to work with. Roger Roger Jolly Saskatoon, Canada. 306-665-0213 Fax 652-0505
